"한국 반도체산업의 경쟁력"

IDEC에서 설계인력양성의 발판을 마련하겠습니다.

IP명 A capacitively coupled CTDSM for sensor readout ICs
Category Analog Application ADC, sensor applications
실설계면적 5㎛ X 5㎛ 공급 전압 1.8V
IP유형 Hard IP 동작속도 320kHz
검증단계 Silicon 참여공정 HM-2001
IP개요 This study presents a sensor readout IC using a capacitively coupled instrumentation amplifier-embedded continuous-time delta-sigma modulator. As the frequency translation effect of chopping and the RRL have a severe side effect, we suggest practical circuit configurations to eliminate chopping artifacts, using chopping frequency as the sampling frequency. The fabricated chip is implemented in 180-nm CMOS technology, and it is able to read out both DC and AC signals.
